The following is a list of books I have read that I recommend for one reason or another. Consider taking the book out at your local library before purchasing a copy.
"Animal, Vegetable, Miracle", Barbara Kingsolver - The author and her family leave a western state and move to Virginia (I think) to live on a farm where the goal is to grow all their own food for a year.
"The Omnivore's Dilemma", Michael Pollan - Read anything Michael Pollan writes. This book really gets you thinking about our food supply.
"Food Rules", Michael Pollan - a very quick read. Helpful tips like - "If you are not hungry enough to eat an apple, you probably are not that hungry."
"The Blue Zones", Dan Beuttner - Researchers have identified places around the globe where it is relatively common for people to live well into their 90's in good health, often working at physical jobs. One such area is here in the U.S. in Loma Linda, California.
"Healthy at 100", John Robbins - I listened to this book on tape. The author goes tries to find the commonalities between societies where it is common for people to live to 100 in good health.
"The China Study" - T. Colin Campbell, Ph.D. - This book is a scientific look at the health effects of the diets of a population and the incidence of disease on that population. Countries that eat a lot of meat have a higher rate of cancer. Countries that eat a high fat diet have a higher rate of cancer. I found this book to be fascinating and highly recommend it.
"King Corn" - not a book, it is a documentary film. If you are a NetFlix customer, look this up. Two recent college graduates set out to follow a corn crop from planting to harvest to feedlot. It seems that in this country, we mostly eat corn. Corn fed beef, high fructose corn syrup, corn oil. Probably a bit too much corn.
